I have been thinking about a timeline I wish to start (don't get too excited, this is the third timeline I have thought about and I haven't started any so far). The POD is before the birth of queen Victoria (around 1810), so i figured that her birth would be butterflied away. This lead me to believe that without Victoria as queen, Hanover would remain in personal union with the UK (I would like to apologise to all Scotisch, Welsh and Irish for the title). The thing is, I want to include Hanover in the attempt of Prussia to unify/conquer Germay. If Hanover remains British this wil be a lot harder. So I want to accomplish some kind of split between Hanover and the UK, but I have no good idea how to do it. So do you have any ideas, preferably in the early/middle of the 19th century)?
